# FE-RB-002 — Chunk or deployment mismatch Trigger on `CHUNK_LOAD_FAILURE`, `RELEASE_MANIFEST_FAILURE`, or `DEPLOY_MISMATCH`. Warn when dirty state may be lost, fetch the manifest `no-store` once, record the release pair, and allow only one reload. The planned release-owner triage target is five minutes. Escalate to the hosting/CDN owner. Close only after entry/lazy assets are reachable, the manifest parses into a coherent tuple, a second automatic reload is blocked, and the critical route smoke passes.
